The secondary objective of the study is the collection and analysis of tumor tissue specimens to enable the development and validation of single and/or multiple-marker ('multiplex') IVD assay(s) for antigen expression profiling. It is a regulatory requirement to develop the IVD(s) as a companion diagnostic(s) to accompany a future new indication drug application(s). Therefore all tumor specimens from this study will be retained by Adaptimmune for companion diagnostic validation purposes.
